Lady GaGa earns an estimated $30 million a year just from her Twitter page. The ludicrously enviable figure, which translates to £18.9 million, is responsible for around a third of her overall $90 million fortune, according to the Wall Street Journal.
It is thought that many of her loyal 20 million followers are encouraged to buy her music legally because of the bond she has created with them.
Marketing expert John Bonini said: "[GaGa] really engages [her followers] and retweets stuff they say as if she was one of them".
The star has more followers on the site than anyone else in the world, with Justin Bieber close behind.
Her fortune may be impressive, but it was recently revealed that it's Taylor Swift who is the top-earning musician in the world.
